What is the function of round bottom flask?
A round bottom flask is called a boiling flask. I tolerates the stresses of heating better than flat bottom or Erlenmeyer flasks.
What is a heating mantle and how do you use it?
A heating mantle is the best way to heat a liquid in a round bottom flask. The heating mantle can be either rigid or soft, but heats the flask by heating an electric coil which surrounds the round bottom flask. Heating mantles come in different sizes to best match the size of the found bottom flask for a snug fit around the entire bottom of the flask. They are commonly used in distillations and other heated reactions.A heating mantle if much better than a hot plate because the heating mantle makes contact with the entire bottom surface of a round bottom flask. It is also much better than a Bunsen burner for heating flammable liquids.See the Related Questions and Web Links to the left for more information.
What is bulb flask and what is it used for?
A round-bottom flask is also called a bulb flask. It's mostly used in heating solutions, as the rounded bottom allows for more uniform heating and/or boiling of liquids.

How do you part salt from water?
we did that experiment in our chemistry lab! and from what i remember we just put the salt water in a beaker covered it with this glass cover and heated the water but not boiled i don't think and when all the condensation is off the bottom of the glass cover(it will turn a kind of crusty white) then you have the salt is left over when the water is all gone in the bottom of the beaker!let me know if this helped!

Experiment to prove that gases are poor thermal conductors?
There are many experiments you can perform in order to prove that gases are poor thermal conductors. You can try heating up an enclosed space from the top and feeling the bottom for example.

The heating of the air goes up while heating and when it gets to the top and goes to the bottom it cools
